INSOLE-TRIMMING MACHINE.

Specification of Letters Patent.

Patented Jan. 22, 191%.

Application filed April 3, 1916. Serial No. 88,510.

To all whom it may concern:

Be it known that I, EUGENE H. TAYLOR, a citizen of the United States, residing at Hyde Park, county of Suffolk, State of li lassachusetts, have invented a'certain new and useful Improvement in Insole-Trimming Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has for its object a machine for trimming the edges of the up-turned rib or lip of an insole after the insole has been otherwise completed. The machine is adapted particularly to trim the rib or lip of insoles of the general type shown and described in United States Letters Patent No. 1,062.53?) dated May 20, 1913. The machine embodying my present invention is small and efficient and is so constructed as to operate with great rapidity and to feed the insole through it with a minimum of effort on the part of the operator. 1

The invention will be fully understood from the following description when taken in connection withthe accompanying drawings and the novel features thereof will. be pointed out and clearly defined in the claims at the close of this specification.

Referring to the drawings Figure 1 is a front elevation of a machine embodying my invention.

Fig. 2 is a side elevation of the machine.

Fig. 3 is a detail showing the relation of the working instrumentalities at the time when the insole is passing through the machine.

Fig. 4 is a view in perspective of an insole of the tvne intended to be operated. upon by the machine.

Referring now to the drawings, at 11 is shown the frame. At 12 is shown the knife, at 13 the feed wheel. at 14 the abutment for the feed wheel and at 15 the presser foot.

At 16 is shown the main shaft provided with a pair of pullev wheels 9 and 10. the former of which is fast on the shaft 16 and the latter of which is loosely mounted thereon. The main shaft extends through the frame of the machine and carries the abutment 14 on the end toward the left hand side of the machine-as viewed in Fig. 1. The abutment 14 coiiperates with the feed wheel 13. in feeding the work through the machine and for this purpose is preferably rotatably mo n d as shown; and is also prefera y so arranged that it is driven at a peripheral speed which is equal to the peripheral speed of the feed wheel 13 by means which will be hereinafter described.

The knife 12 is of .disk shape and the (plane of its cutting edge is substantially coincident with the plane of the adjacent face of the abutment 11 and of the adjacent face of the feed wheel 13. The fiat edge of the knife 12 is in contact with the adjacent face of the abutment or feed wheel 141 and closely adjacent to but preferably not in contact with the adjacent face of the feed wheel 13. The knife is mounted on the end of the knife shaft 17, said shaft being parallel with the main shaft 16. The knife shaft 17 is provided with a collar 18 between which and the frame is located a spring 19 which tends to hold the knife shaft 17 to the left as shown in Fig. 1 so that a portion of the flat edge of the knife is held yieldingly against the adjacent face of. the abutment or feed wheel 14, the latter being provided with a shearing edge which cooperates with the knife 12. The width of the abutment 141 is equal. to the width of the trimmed rib of the insole, and the width of the feed wheel 13 is substantially equal to that of the insole rib. In order that the width of the finished insole may be varied the feed wheel and abutment are threaded to their respective shafts so that wheels and abutments of various widths may be employed.

The feed wheel 13 is mounted on a floating shaft 20 also parallel with the main shaft 16 and the knife shaft 17. The shaft 20 is carried in a floatin frame 8 which is pivoted at 26 to the frame of the machine. The floating frame 8 also supports the short shaft 27 on which the idler gears 23 and 2 1 are mounted. The floating frame is provided with a lug 29 through which passes an adjusting bolt 30. The bolt 30 also passes through a suitable hole 3 1- in the frame 11 and through a hole in an adjusting nut 31 which is threaded into the hole 34. The hole in the adjusting nut 31 is slightly larger than the diameter of the bolt 30 so that the bolt is. capable of being adjusted lengthwise thereof by a suitable nut 32. The hole in the lug 29, through which the bolt passes, is also larger than the shank of the bolt, and the bolt is provided with a flar ing head 3 to permit the lug 29 to move somewhat about the pivot 26.

A spring33 in hole 34 in the frame bears against the lug 29 of the floating frame at one end and against the adjusting nut 31 at the other end. The spring 33 causes the feed Wheel 13 to exert a yielding pressure on the work and at the same time permits the feed Wheel 13 and the abutment or feed wheel 14 to separate as required to permit a thick spot or bunch in the work to pass through. The tension on the spring 33 is regulated by means of the adjusting nut 31, the nut 32 being employed to determine the lowermost position of the feed wheel 13. The feed wheel 13 is preferably s0 positioned with relation to the feed wheel or abutment 14 that they are out of contact when the feed wheel 13. is in its lowermost position in order that the Work may be readily inserted between the Wheels, the relation of the feed wheels and the pressure exerted by the spring being entirely dependent upon the character and thickness of the material operated upon.

The, presser foot 15 is arranged vertically and is pivoted at 4 to an elbow lever 35 which is itself supported on a pivot 36 on the upper part of the frame of the machine. The other arm of the elbow lever 35 is connected by av flexible connection 37 with the treadle 38 by means of which the presser foot 15 may be separated from the feed wheels 13 and 14 to permit the work to be inserted. At 39 is shown a bolt pivotally connected at 40 to one arm of the elbow lever 35 and passing up through a portion of the frame 11. On the upper'end of this bolt 39 is a tension nut 41 and between the tension nut and the frame is placed a spring 42 which holds the presser foot 15 yieldingly against the work. The amount of pressure exerted on the work may be varied by changing the position of the tension nut 41. It will be seen that the parts are so arranged that by moving down the treadle against the spring 42 the presser foot is moved away from the feed wheels to permit the insertion and removal of the work, and that the presser foot will resume its original position when the operator takes his foot off the treadle.

In the operation of the machine the workman inserts the insole with the rib between the rims of the two feed wheels 13 and 14, and the presser foot rests against the opposite face of the insole. The movement of the 7 feed wheels feeds the insole along and the rotary knife 12 cuts off the rib flush with the proximate faces of the two feed wheels. After the insole has been inserted in the machine, no effort on the part of the operator is required to guide it through the machine.

What I claim is:

1. In a trimming machine, the combination of an abutment and a feed wheel cooperating with each other to feed the work, and a yieldingly mounted disk knife having its cutting edge in a plane substantially coincident with the plane of one face of the feed wheel.

2. Ina trimming machine, the combination of an abutment and a yieldingly mounted feed wheel cooperating therewith to feed the work, and a yieldingly mounted disk knife having its cutting edge in the plane substantially coincident with the plane of one face of the feed wheel.

3. In a trimming machine, the combination of an abutment and a yieldingly mount ed feed wheel coii 'icrating tlnu'cwith to feed the work, a yieldingly mounted knife having its cutting edge in a plane substantially coincident with the plane of one face of the feed wheel, and a presser foot operating to hold the insole against the other face of the feed wheel.

4. In a machine of the character described, the combination of a pair of feed wheels, a rotary knife having its cutting edge in substantially the plane of one face of said feed wheels, and means for pressing the said knife yieldingly toward the feed wheels.

5. In a machine of the character described, the combination of a pair of feed wheels. a disk knife having its face in contact with one face of one of said feed wheels, and means for pressing said knife yieldingly against the said feed wheel.

6. In a machine of the character described, the combination of a pair of feed wheels each having an end face in substantially the same plane a disk knife, the axes of said feed wheels and of the knife being parallel, and a spring acting on the disk knife and tending to move it endwise of its axis and toward the said end faces of the feed wheels.

In testimony whereof I aliix my signature. EUGENE H. TAYLOR.
